Boneng PW Planetary Hoisting Gearbox

Boneng PW Planetary Hoisting Gearbox is a core transmission device tailored for hoisting scenarios, integrating professional design and robust manufacturing to meet the high-load, high-reliability requirements of industrial hoisting operations. As a specialized variant for lifting equipment, it inherits Boneng’s mature planetary transmission technology while optimizing structural details for hoisting-specific working conditions, such as frequent start-stop, impact load resistance, and stable torque output.

The gearbox adopts a precision planetary transmission structure, with key components crafted from high-strength alloy steel. Sun gears and planet gears undergo strict carburizing, quenching, and precision grinding processes, achieving high tooth surface hardness, wear resistance, and minimal backlash—critical for precise hoisting positioning. The reinforced planet carrier is designed via finite element analysis to enhance structural rigidity, effectively dispersing load pressure and improving impact resistance.

In terms of performance, the PW series delivers single-stage efficiency exceeding 97%, with a flexible transmission ratio range that can be customized through multi-stage combinations to match different hoisting speed and torque demands. Its compact design ensures high power density, fitting seamlessly into limited hoisting equipment spaces. Imported high-load roller bearings and double-lip oil seals are adopted at key positions, ensuring low-noise operation, reliable sealing, and reduced maintenance frequency in harsh industrial environments.

With 95% modularization, the gearbox supports flexible customization, including horizontal/vertical installation, various input/output interfaces, and matching with different hoisting motors. It is widely applied in construction cranes, port hoists, mining hoisting equipment, and industrial lifting systems, adapting to complex working conditions such as high altitude, heavy load, and continuous operation.

Backed by Boneng’s professional technical support and global service network, the PW Planetary Hoisting Gearbox provides stable and reliable transmission solutions for hoisting industries, safeguarding efficient and safe operation of equipment.
